Given A(2,14), B(2,3), C(4,2), and D(14,2) what is the distance of CD?
42.14
CD
= ?
Answer:
CD = 10 units
Step-by-step explanation:
Coordinates of the given points are A(2, 14), B(2, 3), C(4, 2) and D(14, 2).
Distance between the two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by the formula,
d = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Distance between the two points C(4, 2) and D(14, 2) will be,
CD = [tex]\sqrt{(14-4)^2+(2-2)^2}[/tex]
= [tex]\sqrt{(10)^2}[/tex]
= 10 units
Therefore, distance between C and D is 10 units.

isiah is saving up $1000 for a trip. He already has $550 saved and plans to save an additional $50 each month. how many months (m) will it take him to save up $1000?
Isiah needs to save an additional [tex]\$50[/tex] for 9 months to save [tex]\$ 1000[/tex]
What is division operation?Let there are two integers [tex]p, q[/tex] and we will write these integers in the format of [tex]\frac{p}{q}[/tex], where [tex]q \neq0[/tex].
Isiah has the amount [tex]\$$550[/tex] and he needs to save an additional [tex]\$50[/tex] every month.
His target is to save [tex]\$1000[/tex] for a trip.
Now, he needs to save the amount of [tex]\$1000-\$550[/tex]
[tex]=\$450[/tex]
In a month he will be able to save only [tex]\$50[/tex]
Now, for finding the required result, we need to divide [tex]\$450[/tex] by [tex]\$50[/tex].
The number of the required months will be [tex]\frac{450}{50}[/tex]
[tex]=9[/tex] month.
Therefore, Isiah needs to save an additional [tex]\$50[/tex] for 9 months

Store A charges $1,200 for repairs with a 6 percent sales tax. Store B charges $1,350 with a 7 percent sales tax. Explain how you would determine the amount of money saved by using Store A instead of Store B?
Answer:
The total cost of each repair for each store is also added to the cost of repairs to the sales tax too. Then the amount of money saved will be the difference between the two stores and the cost of repairs.

Find an equation perpendicular to x=1 and passing through (8,-9)
What is the equation (Type your answer in standard form.)
Answer:
[tex]y=-9[/tex]
Step-by-step explanation:
We want to find an equation of a line that's perpendicular to x=1 that also passes through the point (8,-9).
Note that x=1 is a vertical line since x is 1 no matter what y is.
This means that if our new line is perpendicular to the old, then it must be a horizontal line.
So, since we have a horizontal line, then our equation must be our y-value of our point.
Our y-coordinate of our point (8,-9) is -9.
Therefore, our equation is:
[tex]y=-9[/tex]
And this is in standard form.
And we're done!
24. Predict the type of quadrilateral that is formed
by the points of intersection of the lines
3x + y - 4 = 0, 4x - 5y + 30 = 0,
y = – 3x – 1, and - 4x + 5y + 10 = 0. Give
reasons for your prediction. Verify that your
prediction is correct by solving this problem.
Answer:
A PARALLELOGRAM OR A RHOMBUSStep-by-step explanation:
Given the equation of the lines 3x + y - 4 = 0, 4x - 5y + 30 = 0, y = – 3x – 1, and - 4x + 5y + 10 = 0. For us to be able to predict the type of quadrilateral formed by this lines, we need to find the slope of each of the lines. Any two lines with the same slope will be parallel lines.
The standard form of equation of a line is expressed as y = mx+c where m is the slope of the line.
Re-writing each equation in standard format:
For the line 3x + y - 4 = 0;
3x+y = 4
y = 4-3x
y = -3x + 4
Hence the slope of the line is -3
For the line 4x - 5y + 30 = 0:
4x-5y = -30
-5y = -30-4x
-5y = -4x-30
divide through by -5
y = 4/5 x + 6
Hence the slope of this line is 4/5
For the line y = – 3x – 1:
The line is already in its standard format, hence the slope of the line is -3
For the line - 4x + 5y + 10 = 0:
-4x+5y = -10
5y = -10+4x
5y = 4x-10
divide through by 5
y = 4/5 x - 10/5
y = 4/5 x - 2
Hence the slope of this line is 4/5
From the slopes above, it can be seen that the line 4x - 5y + 30 = 0 is parallel to - 4x + 5y + 10 = 0 and that of the line 3x + y - 4 = 0 is parallel to y = – 3x – 1 due to their similar slope.
To know the the type of quadrilateral formed by this lines, first we need to check whether two dissimilar lines are perpendicular to each other. If they are perpendicular to each other, it means the quadrilateral could be a square or a rectangle but if otherwise, it will either be a parallelogram or a rhombus.
For two lines to be perpendicular, the product of their slope must be -1 i.e m1m2 = -1
For the first two lines:
m1 = -3 and m2 = 4/5
Taking their product:
-3*4/5 = -12/5
Since the product did not give use -1, hence the quadrilateral is neither a square nor a rectangle. The quadrilateral can therefore either be a parallelogram or a rhombus since the intersecting lines of either shapes are not perpendicular to each other.

A lion runs 45 mph and crosses a bridge in 40 seconds. A cheetah runs across the same bridge in 30 seconds. How fast does the cheetah run?
Answer:
60 mph because the cheetah runs at 4/3 of the lion's pace, which is 45 mph. 4/3 x 45 is 60.
The cheetah's speed is 60 mph
Average speed is total distance ran per time
Average speed = total distance / time
We are to determine the average speed of the cheetah. The average speed cannot be determined because the distance ran by the cheetah is not provided. The distance has to be determined
Information on the distance run can be determined from the information of the lion provided
45 = total distance ÷ 40
total distance = 45 x 40
total distance = 1800
Average speed of the cheetah = 1800 ÷ 30
= 60 mph

Question
Cable company A charges $45 a month for cable plus a $18 installation fee. Cable B charges $39 a month for cable plus a $30 fee for installation. Which inequality can be used to find out when the monthly cost for Cable company A is less than Cable company B?
a)39x+30<45x+18
b) 45x+18>39x+30
c) 45x+18<39x+30
d)39x+18<45x+30
Answer:
c) 45x+18<39x+30
Step-by-step explanation:
Step 1
We have to find the Algebraic expressions for the cable companies
Cable company A charges $45 a month for cable plus a $18 installation fee.
Let the number of months be represented as x
Hence, this is represented as:
$45 × x + $18
= 45x + 18
Cable B charges $39 a month for cable plus a $30 fee for installation.
Let the number of months be represented as x
Hence, this is represented as:
$39 × x + $30
= 39x + 30
The inequality that can be used to find out when the monthly cost for Cable company A is less than Cable company B?
= Cable company A < Cable company B
= 45x + 18 < 39x + 30
Therefore option c is correct
